System, method and article for controlling the dispensing of insulin

Abstract

An integrated circuit includes circuitry to control a process. The process includes adjusting fuzzy-logic control parameters based on received and retrieved blood glucose-related data, predicting blood glucose levels based on the received blood-glucose-related data, and generating control signals to control dispensing of insulin based on the received blood glucose-related data and the fuzzy-logic control parameters. The process may include predicting blood glucose levels based on the retrieved blood glucose-related data. The process may include transitioning between a post-meal correction protocol and a fasting protocol. The process may include transitioning from a post-meal correction protocol to a fasting protocol when a fasting criteria is satisfied.
